在我的Android应用程序中，我打开了facebook提要对话框，因为加载需要时间我尝试在提示对话框启动之前实现进度对话框，在oncreate（）中我打开了progressdialog但它是没有在这里工作对话框是打开但没有进度对话框，然后我试图放入AsyncTask，现在我可以看到progressDialog但fb feeddialog没有显示..下面是我的代码
public class ShareOnFacebook extends Activity {

如果你正确实现了它，加载弹出对话框时，Facebook提要对话框已经有了自己的加载/进度微调器。
我的应用使用了Feed对话框，它已经有了自己的进度对话框。尝试下载our sample app并验证当您点按“更新状态”时是否看到进度对话框。
